* configure: implement full-repl option.Kaz Kylheku2021-08-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch unbundles the building of the full-featured REPL from HAVE_TERMIOS. We make it subject to its own configuration option CONFIG_FULL_REPL, which is 1 by default. This way, the downstream users or package maintainers can build TXR without the full-featured REPL even if HAVE_TERMIOS is 1, and the other termios material is built-in. * configure (full_repl): New variable. (help): Include full-repl in the help text. In the termios test, if we don't detect termios, then negate the full_repl variable. In the final config variable generation section, generate the CONFIG_FULL_REPL 1 define in config.h, if full_repl is true, ensuring it is subject to HAVE_TERMIOS, too. * linenoise/linenoise.c: Replace HAVE_TERMIOS with CONFIG_FULL_REPL. * linenoise/linenoise.h: Likewise. * parser.c: Likewise. * txr.c: Likewise and ... (if_termios): Macro renamed to if_full_repl. (if_full_repl): New macro. (opt_noninteractive): Use if_full_repl macro for initializing. (banner): Use if_ful_repl macro instead of if_termios.
* listener: additional reductions in non-termios build.Kaz Kylheku2021-08-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * linenoise/linenoise.c (struct lino_state): these members are now absent in non-termios build: atom_callback, ca_ctx, rawmode, mlmode, clip, result, buf, plen, pos, sel, end, len, dlen, dpos, dsel, dend, cols, oldrow, maxrows, history_index, need_resize, need_refresh, selmode, selinclusive, noninteractive and undo_stack. (lino_set_multiline, lino_get_multiline, lino_set_selinclusive, lino_get_selinculsive, lino_set_noninteractive, lino_get_noninteractive, lino_set_atom_cb): Functions now only defined in termios build. (linenoise): Adjustments for missing members in non-termios mode. (lino_make): We no longer need to set noninteractive to 1 in non-termios build. The flag no longer exists. (lino_copy, lino_cleanup): Avoid referencing nonexistent members in non-termios build. (lino_set_result): Another termios-only function. * linenoise/linenoise.h (lino_set_result, lino_clear_screen, lino_set_multiline, lino_get_multiline, lino_set_selinclusive, lino_get_selinculsive, lino_set_noninteractive, lino_get_noninteractive, lino_atom_cb_t, lino_set_atom_cb): Declare only in termios build. * parser.c (repl): Add #if HAVE_TERMIOS to avoid using linenoise features not available in non-termios build, and to remove any variables that thus become unused.

(struct abuf, struct row_values): Struct types defined only if HAVE_TERMIOS. (screen_rows): Defined only if HAVE_TERMIOS. (linenoise): Support only noninteractive read loop unless HAVE_TERMIOS. (lino_make): If HAVE_TERMIOS is false, then set the noninteractive flag, so the linenoise function enters the plain-mode loop. (lino_cleanup, lino_hist_add): Add #ifdefs to avoid calling nonexistent functions when HAVE_TERMIOS is false. * linenoise/linenoise.h (struct lino_completions, lino_compl_cb_t): Define these types only if HAVE_TERMIOS. (lino_set_completion_cb, lino_add_completion): Declare only if HAVE_TERMIOS. * parser.c: Include linenoise/linenoise.h unconditionally. (report_security_problem, load_rcfile, repl_intr, read_eval_ret_last, get_home_path, repl_warning, is_balanced_line, hist_save): Now define regardless of HAVE_TERMIOS. (repl): Define regardless of HAVE_TERMIOS, but don't set completion or atom callback if HAVE_TERMIOS is false. * parser.h (repl): Declare unconditionally, not subject to HAVE_TERMIOS. * txr.c (if_termios): New macro. (opt_noninteractive): Initialize to 1 if HAVE_TERMIOS is false. (help): Text about entering into listener mode is always present now, even in a build withou HAVE_TERMIOS. (banner): Function is always defined. If we don't HAVE_TERMIOS, then the unused string literal that will never be printed is replaced by nil. (hint): Function removed. (txr_main): Blocks conditional on HAVE_TERMIOS that either call banner and go to the repl, or else call hint and exit, are reduced to unconditionally calling banner and going to the repl. All #if HAVE_TERMIOS blocks are similarly replaced with just the HAVE_TERMIOS case.
* listener: prompt feature for plain mode.Kaz Kylheku2021-08-031-0/+1
| | | | | | | | | | | | | | | | | | The :prompt-on command will enable prompting in plain mode. * linenoise/linenoise.c (struct lino_state): New member, show_prompt. (line_enable_noninteractive_prompt): New function. (linenoise): In the plain mode loop, the show_prompt flag is on, show the prompt. For continuation lines, show a condensed prompt, which consists of the suffix of the full prompt, starting on the last non-whitespace character. * linenoise/linenoise.h (lino_enable_noninteractive): Declared. * parser.c (repl): Implement :prompt-on command which enables the above mode. * txr.1: Documented.

* listener: if no new lines, don't save history.Kaz Kylheku2020-02-181-0/+1

* listener: append to .txr_history instead of clobbering.Kaz Kyheku2020-02-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses the problem of history loss that occurs when a user juggles multiple TXR sessions that all clobber the same history file. * linenoise/linenoise.c (struct lino_state): New member, loaded_lines, keeping track of how many of the lines in the history came from loading the history file. Lines between [0] and [loaded_lines - 1] are loaded lines. New lines occur between [loaded_lines] and [history_len - 1]. (lino_hist_add): Reset loaded_lines to zero when creating history for the first time. Not really necessary since the structure starts zero-filled. When a line of history is erased, then it must be a loaded line, unless loaded_lines is zero. Thus, then decrement loaded_lines to account for a loss of a loaded line, but don't decrement below zero. (lino_hist_set_max_len): Setting the max length can cause history to be trimmed, so we must adjust loaded_lines to account for any loaded lines that get discarded. (lino_hist_save): Takes a new parameter which indicates whether to just save the new history by appending it to the given file, or to overwrite the file with the entire history. In either case, once we save the history, we assume that all of our lines are loaded lines and set loaded_lines to hist_len. In the future, this last step will help implement incremental saving mid-way through a sesssion. (lino_hist_load): Error out if there is already a history. With this loaded_lines logic, it really wouldn't make sense to read history more than once. After loading, set loaded_lines to hist_len. * linenoise/linenoise.h (enum lino_file_mode): New enumeration lino_append. (lino_hist_save): Declaration updated. * parser.c (repl): Implement new history saving protocol. The history file is read using a temporary instance of linenoise, which has the effect of trimming it to the required number of lines. This is written to a temporary file, to which the newly entered lines are appended, and which is finally renamed to replace the history file. (lino_mode_str): Add "a" entry corresponding to lino_append. (lino_open): Do the fchmod in the lino_append case also. * txr.1: Documented the new handling of the history file.

* listener: Cygwin fix.Kaz Kylheku2018-05-181-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | We cannot pass raw C wide literals to static_str; this breaks on platforms where wchar_t is two bytes and strings are aligned to only two byte boundaries. That's why TXR has the wli() macro. We don't want to introduce the wli() macro into linenoise, so the two choices are: duplicate the incoming mode strings into dynamic storage with string(), or pass some enum to specify file mode and locally convert to static mode string. Let's go with the latter. * linenoise.c (edit_in_editor, lino_hist_save): Use enum constant for file mode instead of mode string. * linenoise.h (enum lino_file_mode, line_file_mode_t): New enum. (struct lino_os): File opening functions use lino_file_mode_t instead of mode string. * parser.c (lino_mode_str): New static array. (lino_open, lino_open8, lino_fdopen): Take enum mode instead of string. Convert to literal through lino_mode_str table, and pass that literal to static_str.

The 8 factor had been chosen to cover the worst case that every character is mapped to a tab. (struct lino_state): Almost everything char typed turns to wchar_t. The TTY isn't referenced with Unix file descriptors, ifd and ofd, but abstract stream handles tty_ifs and tty_ofs. The ifs member isn't required any more since plain mode is handled via the tty_ifs stream. (mem_t): Declaration removed; now in linenoise.h. (chk_malloc, chk_realloc, chk_strdup_utf8): Declarations removed. (lino_os): New static structure. (nelem): New macro. (wcsnprintf): New static function. (enable_raw_mode, disable_raw_mode): Get Unix FD from stream using lino_os interface.

* linenoise: replace linefeeds with CR in previous result.Kaz Kylheku2017-07-091-1/+1
| | | | | | | | | | | | | | This fixes the issue that when a multi-line result is pasted into the edit buffer with Ctrl-X P, the line breaks appear in it as linefeeds, displayed as ^J. In linenoise, we need line breaks to be carriage returns. * linenoise/linenoise.c (lino_set_result): replace newlines with carriage returns in the given string. * linenoise/linenoise.h (lino_set_result): Add comment that function takes ownership of memory assumed to be malloced, and that it modifies it.
* linenoise: callback for checking syntax completeness.Kaz Kylheku2017-06-161-0/+3
| | | | | | | | | | | | | | | | | | | The idea is that when the user types Enter to submit a line, it can be checked whether it is complete syntax using a callback. If the callback indicates that the syntax is incomplete (there are open expressions, string literals or whatever), then Enter is inserted verbatim. This is active in multi-line mode only. * linenoise.c (struct lino_state): New members, enter_callback and ce_ctx. (lino_set_enter_cb): New function. (edit): If enter is issued, and multi-line mode is in effect, and there is an enter callback, then call it. If the callback returns false, then just insert the character. * linenoise.h (lino_enter_cb_t): New typedef. (lino_set_enter_cb): Declared.
* linenoise: support forcing of noninteractive mode.Kaz Kylheku2017-04-041-0/+2
| | | | | | | | | | | | * linenoise/linenoise.c (struct lino_state): New member, noninteractive. (lino_set_noninteractive, lino_get_noninteractive): New functions. (linenoise): Check noninteractive flag; if set, treat the situation like !isatty(ls->ifd). * linenoise/linenoise.h (lino_set_noninteractive, lino_get_noninteractive): Delared.
* linenoise: Ctrl-X Ctrl-P edits result of command.Kaz Kylheku2016-10-121-0/+1
| | | | | | | | | | | | * linenoise/linenoise.c (struct lino_state): New member, result. (edit): Ctrl-P or p in extended mode cause result string to be inserted into the buffer. (lino_copy): Ensure result string in copy is null. (lino_cleanup): Free result string and set to null. (lino_set_result): New function. * linenoise/linenoise.h (lino_set_result): Declared.
* linenoise: support inclusive selection.Kaz Kylheku2016-05-191-0/+2
| | | | | | | | | | | | | | * linenoise/linenoise.c (struct lino_state): New mode flag, selinclusive. (lino_set_selinclusive, lino_get_selinclusive): New functions. (sync_data_to_buf): Adjust rightmost endpoint when selection is reversed and inclusive mode is in effect, so that the included character will be visually highlighted. (yank_sel, delete_sel): Adjust endpoint of selection if in in inclusive mode. * linenoise/linenoise.h (lino_set_selinclusive, lino_get_selinclusive): Declared.

* linenoise: substring flag in completion callback.Kaz Kylheku2015-10-031-0/+1
| | | | | | | | | | | | | | | | | | | A feature is hereby introduced into linenoise whereby completion mode can be entered via Ctrl-X Tab also, not only Tab. This is distinguished with a flag in the completion structure. The intent is that the callback can use this to provide substring matches not only prefix matches. * linenoise/linenoise.c (complete_line): Takes a new argument, and stores it in the new substring member of lino_completions_t. (edit): If Tab is typed while in Ctrl-X extended mode, then fall through to the regular switch, where the TAB case now recognizes that it is in extended mode and passes the mode flag to complete_line. * linenoise/linenoise.h (lino_completions_t): New member, substring.
* linenoise: atom-gathering callback feature.Kaz Kylheku2015-09-181-0/+3
| | | | | | | | | | | | * linenoise/linenoise.c (struct lino_state): New members atom_callback and ca_ctx. (lino_set_atom_cb): New function. (edit): Ctrl-X Ctrl-A invokes atom callback, and inserts returned string. * linenoise/linenoise.h (lino_atom_cb_t): New function pointer typedef. (lino_set_atom_cb): Declared.
* linenoise: support suffix on temp file name.Kaz Kylheku2015-09-181-0/+1
| | | | | | | | | | | | | | This is so that when a command line is edited in an external editor, editors can choose appropriate syntax highlighting mode based on the suffix. * linenoise/linenoise.c (struct lino_state): New member, suffix. (edit_in_editor): If we have the mkstemps function, then use it to create a suffixed name. (lino_set_tempfile_suffix): New function. * linenoise/linenoise.h (lino_set_tempfile_suffix): Declared.
* Listener configuration variables.Kaz Kylheku2015-09-171-0/+1
| | | | | | | | | | | | | | | | | | * linenoise/linenoise.c (lino_get_multiline): New function. * linenoise/linenoise.h (lino_get_multiline): Declared. * parser.c (listener_hist_len, listener_multi_line_p_s): New symbol global variables. (repl): Set linenoise history length and multi-line mode from the *listener-hist-len* and *listener-multi-line-p* variables on each call. Set the *listener-multi-line* variable from the lino_t object's current state after each linenoise call. (parse_init): Initialize new global variables and register them as special variables. * txr.1: Update sentence which says that history is fixed at 100 lines. Document listener configuration variables.
* linenoise: lino_copy function.Kaz Kylheku2015-09-111-0/+1
| | | | | | | | | | | | * linenoise/linenoise.c (link_into_list, unlink_from_list): New static functions. (lino_make): Use link_into_list instead of open-coded list manipulation. (lino_copy): New function. (lino_free): Use unlink_from list instead of open-coded list manipulation. * linenoise/linenoise.h (lino_copy): Declared.
* linenoise: remove input-viewing debug function.Kaz Kylheku2015-09-091-1/+0
| | | | | | | | | | | | This is unused code which just addds to the executable size. Also it passes a char to isprint, which is undefined behavior if that char happens to be negative. * linenoise/example.c (main): Remove --keycodes option and reference to lino_print_keycodes function. * linenoise/linenoise.c, linenoise/linenoise.h (lino_print_keycodes): Function removed.
* linenoise: error code distinguishes interrupt from eof.Kaz Kylheku2015-09-061-0/+11
| | | | | | | | | | | | | | | | | | In this commit, we introduce a persistent error variable stored in the lino_t structure, and functions to access it. * linenoise/linenoise.c (struct lino_state): New member, error. (enable_raw_mode): Don't set errno to ENOTTY; set linenoise error to lino_notty. (complete_line, edit, go_raw, linenoise, lino_hist_save, lino_hist_load): Set linenoise error before returning -1. (lino_get_error, lino_set_error): New functions. * linenoise/linenoise.h (enum lino_error, lino_error_t): New enum. (lino_get_error, lino_set_error): Declared.
* linenoise: get rid of globals; everything in struct.Kaz Kylheku2015-09-041-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * linenoise/linenoise.c (completion_callback, orig_termios, rawmode, mlmode, history_max_len, history_len, history): Global variables removed; moved into struct lino_state. (struct lino_state): New members next, prev. New members completion_callback, orig_termios, rawmode, mlmode, history_max_len, history_len, history. (lino_list): New static variable: dummy node for circular list of struct lino_state structures. (lino_set_multiline): Operate on structure rather than global variable. (enable_raw_mode, disable_raw_mode): Operate on structure. Use file descriptors from structures rather than inconsistent hard-coded use of STDIN_FILENO and the argument fd, which is gone. (lino_clear_screen): Obtain file descriptor from structure, rather than global. (complete_line): Operate on structure rather than globals. Pass context to completion callback. (lino_set_completion_cb): Store callback in structure rather than global. Store new context argument also. (reresh_line): Take mode from structure rather than global. (edit_insert, edit_move_end): Operate on struture rather than globals. (edit): Do not accept file descriptor arguments. Do not update ifd and ofd members of structure; just rely on these values to already be there, since the lino_make constructor puts them there. (lino_print_keycodes, go_raw): Operate on structure. (lino_make, lino_free): New functions. (lino_cleanup): New static function. (linenoise, free_hist): Operate on structure. (atexit_handler): Loop over all structures in global list, and clean up each one. (lino_hist_add, lino_list_set_max_len, lino_hist_save, lino_hist_load): Operate on structure. * linenoise/linenoise.h (lino_t): New typedef. (lino_compl_cb_t): Function type takes new context argument. (lino_set_completion_cb, linenoise, lino_hist_add, lino_hist_set_max, lino_his_save, lino_hist_load, lino_clear_screen, lino_set_multiline, lino_print_keycodes): Declarations updated. * linenoise/example.c (completion): Take new context argument, and ignore it. (main): Create linenoise context with lino_make, giving it the input and output file descriptor, and pass it to all functions.
* linenoise: change naming to conform to project.Kaz Kylheku2015-09-041-12/+12
| | | | | | | | linenoise/linenoise.c, linenoise/linenoise.h: Renaming all camel-case identifiers to underscores. The verbose linenoise prefix becomes lino_. All caps enum tag gets lower cased. Static functions with linenoise prefix lose the prefix.
* linenoise: compile as C++ and use checked allocator.Kaz Kylheku2015-09-041-13/+0
| | | | | | | | | | | | | | | | | * linenoise/linenoise.c (mem_t): New typedef, compatible with the one in lib.h, which we don't want to include. (chk_malloc, chk_realloc): External declarations added. (unsupported_term): Make element type const char *. (linenoiseAddCompletion): Use checked allocator, add casts, use the superior "sizeof *dest_pointer_var" expression in size calculations rather than "sizeof (maybe_wrong_type)". (abAppend, linenoiseHistoryAdd, linenoiseHistorySetMaxLen): Likewise. * linenoise/linenoise.h: Remove unnecessary include guards; we don't use them in this project. Remove 'extern "C"'; we don't require C linkage when compiling everything as C++.
* Add linenoise library.Kaz Kylheku2015-09-031-0/+68
* LICENSE: Add Linenoise authors to the list of copyright holders. * linenoise/LICENSE: New file. * linenoise/linenoise.c: New file. * linenoise/linenoise.h: New file.
